Biology and ecology of weeds
Author: W. HolznerPublisher: Springer Science & Business Media
ISBN: 9401709165
Category : Science
Languages : en
Pages : 446
Book Description
Weeds are a fascinating study for specialists, not only because of their economic importance, but also since in this case biology must be combined with history and agriculture (and its economic aspects). Thus, weed scientists may be concerned with pure basic research, concentrating on general aspects, or with applied science, i.e. having a practical orientation. One of the aims of this book is to create a synthesis between these two branches of study and to review the literature of both fields. The agrestals, the weeds of arable land ~ the most important group from an economic point of view ~ was chasen as the main topic. Other weed groups could only be mentioned briefly (e.g. grassland weeds), or superficially (e.g. aquatic weeds), or had to be omitted completely (e.g. ruderals, because they are so heterogeneous), to keep this volume to an acceptable size and price. Nevertheless, nearly all subsections of botanical science have been treated.
Sesbania In Agriculture
Author: Dale O. EvansPublisher: CRC Press
ISBN: 1000311287
Category : Science
Languages : en
Pages : 191
Book Description
Sesbania, a member of the legume family, has been the object of study in new efforts to discover, conserve, and use plant genetic resources. This volume brings together the most recent research on the subject and combines it with previous studies and an extensive review of the literature. This work is a synthesis of biological description and applied studies related to the highly variable and versatile Sesbania species. Sesbania occurs in both annual and perennial forms in tropical and subtropical regions and is adaptable to an unusually wide variety of soil conditions, including saline. The most important uses of the plants are in nitrogen fixation (as in green manures) and in cropping systems. Auxiliary uses of the different species are as sources for pulp fibers, fuel wood, animal fodder, and wind-breaks.
